PrAlO3−PrAl11O18 Eutectic: Its Microstructure and Spectroscopic Properties
Abstract
The praseodymium aluminum perovskite-praseodymium hexaluminate (PrAlO <sub>3</sub>-PrAl<sub>11</sub>O<sub>18</sub>) eutectic has been studied for the first time. It has been grown by the micro-pulling down method from a composition of 20.7% Pr<sub>2</sub>O<sub>3</sub> and 79.3% Al<sub>2</sub>O <sub>3</sub>. The PrAlO<sub>3</sub>-PrAl<sub>11</sub>O<sub>18</sub> eutectic tends to grow as a fibrous microstructure, with the PrAlO<sub>3</sub> phase forming microfibers that are packed in a matrix of the PrAl<sub>11</sub>O <sub>18</sub> phase. The eutectic has been grown with different pulling rates (p.r.'s): 0.15, 0.3, 0.45, 1, and 5 mm/min. The smallest microfibers were obtained with p.r. = 5 mm/min and are 300 nm in diameter. To the authors' best knowledge, this is the first report of the crystalline phase of PrAl <sub>11</sub>O<sub>18</sub>. The absorption and luminescence spectra of the eutectic are presented. The fibrous/rodlike eutectic self-organized structure obtained in this work has the potential for application in modern photonics in the field of photonic crystals and/or metamaterials.
